Tagging!!I have twice now had the vial turn blue on me and the checker reads 200 blinking. Do you know what causes this?
I test right again and it comes out normal.
TIA

When you say “test again”, what do you mean? New bottle, new liquid and do the entire process again?
Phosphates can potentially bind to the inner cuvettes even after rinsing with RODI. You can acid wash your glassware which might help reduce potential contamination. Our HI7061L GENERAL PURPOSE CLEANING SOLUTION is a dilute hydrochloric acid which could work for cleaning the inside of your cuvettes. Make sure there is no debris in the cuvette with the phosphate test as that will great impact results. We have not received any complaints of bad reagent lot numbers.I'm having almost the same experience from some reagent I just bought, LOT H114 with an expiration of 05/20. I got the blinking 200 then I diluted my sample with 1/2 tank water and 1/2 RO water and got a reading of 17.
So people are suspecting that only certain packets are bad and not the whole LOT?
